1872.1 225 
As might have been expected, the conclusion of the scholarly Zeller is in favour of 
such corrections being made. I hail Mr. Smith as a convert to this view; and he 
has applied the principle with such rigour that the Methoca ichnewmonides of 
Latreille becomes ichnewmonoides (p. 5). Such is my laxness, that I should 
probably have allowed ichnewmonides to pass muster. 
Amongst the minor blemishes of this Catalogue, there is a want of uniformity 
in the abbreviations employed and in the mode of citation of the very same work. 
Take e. g. Curtis’s British Entomology; it is well known that the plates are 
numbered consecutively throughout the whole work, and do not commence afresh 
with each volume, and that the text is not paged, but each leaf bears the number 
of the plate to which it belongs. In the Catalogue, sometimes the volume and 
plate are both indicated, at other times only the number of the plate; and in the 
ref -ences to the text, the unnumbered second page of a leaf is generally referred 
t¢ ma manner which will be best explained by an example. Thus, at p. 22, we 
f id “ Odynerus scoticus, Cur. B. E. iii. pl. 138,” and “ O. pictus, Cur. B. H. iii. 138.” 
‘he reference to the plate is erroneous, O. scoticus not being figured; and both 
/ O. scoticus and O. pictus are mentioned (they cannot be said to be described—but 
they are mentioned) not on the leaf of text which belongs to p!. 138, but on the 
back or second side of leaf 137, so that if iii. 1837 was not thought sufficiently 
definite, the correct reference would have been iii. 137 (b). The same thing occurs 
at p. 32, where Panurgus lobatus, Cur. B. H. iii. pl. 102, should be iii. 101 (6); and 
at p. 36, where Megachile Leachella, Cur. B. E. v. 219, should be v. 218 (6). 
Altogether I find no less than five different forms of reference to Curtis’s plates, 
exclusive of the form of reference to the text; thus— 
p- 5. Tiphia minuta, Curt. Brit. Ent. xiv. pl. 644 [it should be pl. 664]. 
p- 12. Gorytes bicinctus, Cur. B. EH. v. pl. 524 [it should be xi. ]. 
p- 15. Crabro subpunctatus, Cur. B. E. xv. pl. 80 [it should be pl. 680]. 
p- 18. Diodontus insignis, Cur. B. EH. xi. 796 [t.e. the text: it should be 496]. 
D. gracilis, Cur. B. E. xl. pl. 496 [it should be xi.]. 
p- 23. Colletes fodiens, Cur. B. Hi. ii. f. 85. 
p- 37. Heriades truncorum, Cur. B. EH. pl. 504. 
So also, we have “ Fab. Ent. Syst.” and “Fab. H.S.;” “‘Latr. Hist. Nat. 
Crust. et Ins.” and “ Latr. H. N.;” ‘“ Zett. Ins. Lapp.” and “ Zett. I. L.;” &e. 
And, whilst on the head of uniformity, it may be well to note the diversity 
between the form in which, under precisely similar circumstances, consecutive 
species are sometimes catalogued. Take e. g., Megachile versicolor, pyrina, and 
odontura (p. 36); or Osmia parietina and pilicornis (p. 38). M. pyrina and O. 
parietina follow the form usually employed,in the List; but the other three do 
not. Moreover, under M. versicolor, a reference should be supplied to Zool. 1844, 
p. 697 ; and under M. odontwra to Zool. 1849, App. p. lviii. 
Occasionally we find the page correctly given, but the volume omitted. For 
instance, in the references to Sphew gibba, Lin. (p. 6), to Larra pompiliformis, Spin. 
(p. 10), to Apis vestita, Fab. (p. 28), to Hylewus florisomnis, Fab. (p. 37, the pages 
of H. florisomnis and mawillosus have somehow been interchanged), to Osmia 
Leaiana, Spin. (p. 88), to Anthophora retusa, Blan. (p. 39), and to Apis hortorum» 
*In the Ent. Ann, 1872, p. 102, Mr. Smith includes Methoca ichnewmonoides amongst the 
Fossores.—J. W. D.
